The Concentration Meter B33 displays real-time information of the measured concentrations and measures with an exceptionally high accuracy up to +/- 0.0001 wt% (= 1 ppm). The concentration meter can offer this high accuracy due to the new sensor materials that are used. Another advantage is the extremely high chemical resistance of the wetted parts which makes the instrument suitable for a wider range of applications.

The concentration meter has an innovate modular design, consisting of two boxes with the electronics and liquids separated. The sensor box employs one sensor which measures the sound velocity, electrical conductivity and temperature at the same time. The three measured physical parameters are used to calculate and define the two concentrations of a liquid solution.

Easy installation
The modular design of the B33 results in very easy installation. The installation and replacement has never been so easy and is done in four steps. Typical places for installation are in concentration management systems or other systems which are used for chemical supply in the production process of semiconductors, solar panels, LCD displays or in the chemical industry.
